APPARATUS FOR SANDING RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 424,933, dated April 1,1890. Application filed December 28 1889. Serial No. 334,722. (Nomodel.)

To all whom it may concern.-

Be it known that I, HENRY O. NOBLE, a citizen of the United States, anda resident of the city of Brooklyn, county of Kings, and State of NewYork, have invented a certain new and useful Improvement in Apparatusfor Sanding Railways, of which the following is such a full, clear,concise, and exact description as will enable others skilled in the artto which my invention appertains to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

The object of my invention is to provide a sanding apparatus having atube for directin g the sand to the rail, capable of convenientattachment and ready removal, and not liable to be broken when broughtin contact with obstructions. To accomplish this object I provide aflexible tube formed of coiled wire and preferably secured to thecylinder of the sander by means of lugs, which, when the tube is twistedabout the lower end of the cylinder, project between the coils, and myimprovement, while capable of use with other forms of sanders, is shownin connection with an apparatus for sanding railways invented by me andfor which Letters Patent of the United States No. 398,174: were grantedFebruary 19, 1889.

In the accompanying drawings, Figure 1 is an enlarged detailed View ofcylinder with improved wire tube attached. Fig. 2 isa sectional View ofportion of street-car, showing improved apparatus; and Fig. 3 is asectional view of hopper and cylinder, showing lugs for securing tube.

The hopper A, for holding the sand, is attached to the upper flange orrim of the cylinder a, set in the car-floor B, and is shown as providedwith avertically-moving valve 0, mounted on stem 0', upon which are thecrosspieces or fingers 0 for loosening the sand. Upon the cylinder a arepreferably formed two lugs a a, for securing the flexible tube cl, whichis formed of coiled wire. The cyl-' inder a is further shown as providedwith a slotted opening. at its side for receiving the lever e, whichlever projects into or through a slot or socket in the stem 0, the otherend of the lever being secured to the shaft operated throughconnecting-levers g g and footbutton 72-. Also secured to the shaft isleverarm 1', the free end of which is attached to the retractive spring*6, so that when the pressure is relieved from the button h the shaft isimmediately turned back and the valve 0 brought to its seat, avoidingdanger of wasting the sand.

If desired, instead of the lugs on a a a groove may be formed on thesurface of the cylinder a, or the tube (Z may be connected in anyconvenient manner. It is easily seen that a tube formed of a coiled wirelike (I is readily attached and removed, while not likely to becomeloose when in use, and being flexible will give way and bend whenbrought in contact with obstructions, and thus not nearly so liable tobe broken as the rigid metal pipe heretofore used.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a sanding apparatus, thecombination of an outlet-cylinder for the sand and a flexiblecoiled-wire tube secured thereto, substantially as and for the purposeset forth.

2. In a sanding apparatus, the combination of a hopper A, cylinder a,secured beneath said hopper and provided with lugs'a a, and a flexibletube (1, adapted to be attached to said cylinder by means of said lugs,substantially as described.
